Lamp

The lamp in this projector operates for approximately 1,000 cumulative hours, depending on the usage environ- ment. It is recommended that the lamp be replaced after 900 cumulative hours of use or when you notice a significant deterioration of the picture and color quality. The lamp usage timer can be checked with the On-screen Display. (See page 34.)

CAUTION

•Intense light hazard. Do not attempt to look into the aperture and lens while the projector is operating.

•As the usage environment can vary significantly, the projector lamp may not operate for 1,000 hours.

•“1,000 hours” above indicates average life span and should be used for reference only. This is different than the warranty period.

•For safety, the power will not be turned on from the fourth times when turning on the power without changing the lamp after use for 1,000 hours.
